Feature: Implement a way for visual component to communicate with LSP

[noklam]

Two possible solutions:

1. Through the lspClient sendRequest method, we will need to create those request manually.
2. Create a VSCode command and using callback to trigger the command.

I have experimented with the Command approaches, it didn't trigger the Go To definition properly.

Request/Response usually comes with a pair, but now we basically want to do this

1. Send request Execute command
2. Send Response with a "TextDocument/Definition" type

I will continue to explore if this approaches work. The benefit of this is we can keep most of the logic in Python and make use of the pygls library.

Backup plan for this is actually sending a proper "TextDocument/Definition" request from the frontend and handle the logic with specific paramaters that Kedro LSP would understand.

I implemented a PoC here, in the final integration we don't need the command but it's useful for testing.
